to one arm of the quadrant 'or heike-rank v lever in the top. of the tankiivllichllas a i 15 llexible connection at the side of the tank having the. hin delivery spout for conve ving thewater that tloivs from the bottom of the tank to the engine tender.

Frein practical observation, l have dis- 'rovered that the present method of connecting the controlling valve for the tank outlet. thereis always an execs-s pressure ou the valve when closed, of'an extentI at least that of the weight of the connecting rod that joins theLvalve and thequadrant lever at the top of the tank-,Which excess pressure tends to wear the valve and unnecessarily reduces its ellciency' and length of use.

v shown Again, in the use of the present type of connections between the valve llever and the quadra nt lever there are always present, conditions that tend to cause the valve toimproperly engage its seat and thereby cause' a consequent leakage from the tank.

My invention seeks to overcome'the ol jections above noted in the use of the water delivering controls for tanks and to provide a simple, inexpensive andeasily applied de` vice for connecting the operating rod with the tank lever and in such a manner that a considerable saving oli-the maintenanceA of tank valve 1s eected, and to such ends my invention consists 1n the peculiar arrangenient and coperative' connection of the' parts hereinafter fully described, specilically pointed ont.` in the appended claim. and illustrated' in the accompanying drawings, inwhich: i 'be Figure 1, is a vertica section, arts in in si e elevation, of a water tanrlt with micir improved valve connection device applied. 2, is a perspective view, parts being in section of the valve device and the lower end of the connecting device that coperaties with the valve lever, the said device being X'EILAX,

In the drawing, 1 designates the tank, 2 the .valve seat, that is coupled to the ejecting' pipe 3 that extends discharges into the'delivery spout l hinged to the side of the tank.

5 designates the hinged drop valve that copcrates-with the seat 2, and has the usual lou'g lever member 50. 6 designates the quadrant or bell crank lever in the top of device and the valve l'ver .e parts being at their normalpositio .Flg. 4, 1s an end i 5` Y 1s a plan view of the Same, parts iti Y under the tank and the tank, T the flexible member that extends through the top of the tank jacent the spout 4, and 8 counterpoise connection that joins with the spout l and the tank, all of the vabove being of the well known construction now in conlmon use on railroads. 'i

My invention is embodied in the means for Connecting the hell crank lever 6 with the valve lever o0. and the same consists of and hangs adnates 1n an elongated slotted voke 11 that straddles the valve'lever 50.'

In practice, the length vof the rod 10 designates the l0 whose lower-'end termi.v

such that when the valve is closed, and

undernorinal conditions. the lever 50 projects through the volte 1l midway its length, so as to be entirely free m connection with the rod yoke 11. arrangin the lever 5U and the rod 10 is, all weight- (other than that ofthe valve lever itself) on the valve 5., is overcome and since the rod 10 is readily adjustablel by a turnbnckle so'that it will hang suspendedfrom the lever 6 at the top free from connection with' sure whatever on the tank valve 5. c

For guiding the rod 10 and to hold it to its true 'tion relatively to the lever 50, and-furthiiis'l for eliminating the danger of the parts rictionally lever and when valve freely returns to its normal position, I have provided guide devices mounted in the leveras shown. The sist of a pair of link plates 12-12 joined by cross bolts 13 that pass through the lever 50 and receive the nuts H ll. Spacing sleeves 15 are mountedon the bolts 13 .it each side of the lever that act as friction The object. in thus guide devices con eliminat any' pres'- V gripping during the t e rollers, for engaging the oppositeledges of the yoke end of the suspended rod 10, as

4 it bendsrto swing laterally on the lever 50.

By reason lof my improved device, when I the tank spout is swung down in the usual 10:y and a limited free riding of the yoke; end thereof on the lever, it is obvious that any slightfcontraction of the rod 10, particularly invery cold Weather, would have no eiect whatsoever on the valve 5 .and hence danger of a slight lift. of the valve and unnecessaryl leakage of the Water from the tank 1s overcome. What I claim:

l In a valve control for water deli\'e1' \f meansof the character stated, and in which is included a hinged drop valve having a lever member, .a lifting connection for the said member that comprises a slotted yoke through which the lever member extends-and in which it has free movement, and means on the lever member for holding the yoke and the said member from separation, the

said means includindstuds on the lever having roller 2bea-rings between which the yoke end oftlie lifting rod plays'.
